Tell me about the benefits of diseases to animals and plants?

The negative effect is very simple, that is, it cures diseases and causes death. Because the virus has a simple structure, if it simply exists, it can only be regarded as a large chemical molecule. Since there is no basic system necessary for metabolism, the virus itself cannot Replication. But when it comes into contact with a host cell, it takes off its protein coat, and its nucleic acid (gene) invades the host cell. With the help of the latter's replication system, it replicates new viruses according to the instructions of the viral genes.

Benefits of viruses

1. Bacteriophages as viruses can be used as specific drugs to prevent and treat certain diseases. For example, burn patients apply Pseudomonas aeruginosa phage dilution to the affected area

2. In cell engineering, certain viruses can be used as cell fusion promoters, such as Sendai virus

3. In genetic engineering, viruses can be used as vectors for target genes so that they can be spliced ??into the chromosomes of target cells

4. Viruses added to a specific bacterial culture medium can remove impurities

5. Viruses can be used as carriers for precision-guided drugs

6. Viruses can be used as effective pesticides

7. Viruses also play a key role in the material circulation and energy exchange of the biosphere.

8. Viruses can also be used to treat diseases, such as cancer

As an impact: Although viruses are very lethal and effective in treating diseases, they play an unusual role in the survival and evolution of organisms. and vertebrates have obtained more than 100 genes directly from viruses, and humans' own enzyme system for replicating DNA may also come from viruses.
